Prior preclinical and clinical studies have shown that tumors from patients with advanced melanoma contain tumor-infiltrating lymphocytes (TIL) with anti-tumor reactivity. These TIL can be expanded in the laboratory to large numbers, and reinfused to the patient. Using a chemotherapy regimen that selectively kills lymphocytes, a single institution Phase II study of 35 patients showed a 51% objective response rate to TIL and interleukin-2 injection. In the present trial we would like to investigate whether we can achieve similar results in a Hadassah Phase II study, and to determine the feasibility of applying this approach to patients with advanced melanoma who currently have few treatment options.

Patients will have a melanoma metastasis resected and cultured in IL-2 in vitro. Tumor infiltrating lymphocytes from these cultures will be assessed for tumor reactivity and those with such activity will be further expanded and adoptively transferred. Patients will receive a non-myeloablative lymphocyte-depleting preparative regimen consisting of cyclophosphamide (60 mg/kg/day x2 days IV)and fludarabine (25 mg/mE2/day IV x5days). Following this regimen, patients will receive an intravenous adoptive transfer of at least 10E9 tumor-reactive lymphocytes followed by high dose IL-2 (720,000 IU/kg/dose IV every 8 hours for up to 15 doses).
